Re: [flexcoders] AS3 :: RegExp :: String constructor taking out \s slasshes etc.

Hi Peter,

Yeah, hehe no newbie here, just curious about the slashes, and you "string literal" just popped the answer for me. It has nothing to do with the regexp just the string literal ;-)

Thanks for the reply.

Peace, Mike

The slashes are being removed when you use them in a string literal. Did you try a regexp literal?

var pattern:RegExp = /^\s*(package\s(.*){)/g;

Otherwise, it's double slashes...

Hello,

I am here using regular expressions and for some reason didn't relaize that when you create an _expression_ like :

var packages:String = '^\s*(package\s(.*){)';

pattern:RegExp = new RegExp(packages, "g");

will trace :

/^s*(packages(.*){)/g

Notice where the ^s are together, there should be a back slash to say space character.

I tried with both " and ', dosn't make a difference. So obviously you need to double backslash a special charatcer in regular _expression_ strings.

This sucks big time, the reason is I have a parsing library full of registered regular expressions.

Am I seing this right? This is the way it always has been? I guess using php, it is different with how it treats a "RegExp" through it's methods.

Anyway,

Does anybody see any negative effects from using an actual RegExp object in the static library ? Would this cause any confilcts because some internal properties of the RegExp object are not reset or updated correctly. I know the modifiers would have to be flagged correctly.

I use a;

var pattern:RegExp =  RegExpLibrary.getPattern(RegExpLibrary.PACKAGE_PATTERN, "g") as RegExp;

Any thoughts?

Peace, Mike
